Abstract

Science, technology, engineering, arts, and mathematics (STEAM) have been applied in various countries because they have been able to answer the challenges of the globalization era. The implementation of STEAM at school has demanded that teachers have a role in making a relationship between disciplines in science contained in STEAM. The purpose of this research was to describe the perceptions of experienced teachers about math-focused STEAM learning. The research was a descriptive study on 14 vocational high school mathematics teachers in Malang, Indonesia. They had 20-30 years of teaching experience. Data were collected using essay questionnaires. The result showed that their perceptions of STEAM learning were positive. However, they also said that there were several obstacles to math-focused STEAM learning. The first obstacle was the unavailability of supporting literature. The second obstacle was that there were teachers who have no received training. The third obstacle was only a limited number of mathematics material that can be applied in STEAM learning. Additionally, the teacher stated that mathematics was more suitable as supporting contain in STEAM learning than as the primary focus.

Abstract

Salah satu jenis penalaran yang memegang peranan penting dalam pembelajaran matematika adalah penalaran analogi. Salah satu manfaat yang diperoleh siswa ketika menggunakan penalaran analogi dalam pembelajaran matematika adalah meningkatnya kreativitas dalam menyelesaikan dan memecahkan masalah. Analogi dilakukan dengan mencari kemiripan penyelesaian dari dua masalah matematika. Oleh karena itu, penelitian yang berkaitan tentang profil penalaran analogi siswa sangat diperlukan untuk memperoleh deskripsi pada setiap tahap penalaran analogi yang dilakukan oleh siswa. Tujuan dari penelitian ini adalah mendeskripsikan profil penalaran analogi siswa dalam memecahkan masalah trigonometri dengan adversity quotient sebagai peninjaunya. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan enam siswa sebagai subjek. Enam siswa tersebut merupakan siswa kelas XI MIPA SMA Negeri 1 Purwosari yang memiliki 3 AQ berbeda dengan masing-masing 2 siswa pada setiap tipe. Data dikumpulkan menggunakan tiga instrumen, yakni lembar angket ARP, lembar tes penalaran analogi, dan pedoman wawancara. Proses analisis data ini terdiri atas reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian ini menunjukkan bahwa terdapat perbedaan profil penalaran analogi siswa pada setiap tipe AQ. Siswa climber dapat melakukan semua tahapan penalaran analogi yang disusun oleh Sternberg. Siswa camper dapat melakukan tahap encoding dan memenuhi satu indikator pada tahap inferring. Siswa quitter hanya dapat melakukan tahap encoding. Kata kunci: penalaran analogi, pemecahan masalah, adversity quotient Abstract: One type of reasoning that plays an important role in learning mathematics is analogical reasoning. One of the benefits that students gain when using analogical reasoning in learning mathematics is increased creativity in resolving and solving problems. Analogy is achieved by identifying similarities in the solutions of two mathematical problems. Therefore, research related to students' analogical reasoning profiles is very necessary to obtain descriptions of each stage of analogical reasoning carried out by students. The aim of this research is to describe students' analogical reasoning profiles in solving trigonometry problems with the adversity quotient as the observer. This research used a descriptive qualitative approach with six students as subjects. The six students are class XI MIPA students at SMA Negeri 1 Purwosari, each with three different AQs, with two students in each category. Data were collected using three instruments: the ARP questionnaire sheet, analogical reasoning test sheet, and interview guide. The data analysis process consists of data reduction, data presentation, and drawing conclusions. The results of this research indicate that there are differences in the analogical reasoning profiles of students in each type of AQ. Climber students can carry out all the stages of analogical reasoning as compiled by Sternberg. Camper students can carry out the encoding stage and fulfill one indicator at the inferring stage. Quitter students can only carry out the encoding stage. Keywords: analogical reasoning, problem solving, adversity quotient

Abstract

Math problem-solving skills are essential to train students' logical and analytical thinking, but they are often challenging at the elementary school level due to students' difficulties in understanding initial concepts and digesting the material. This study aims to analyze the thinking process of grade V students of SDI Al Ghaffaar Malang in solving problems of KPK and FPB materials through written tests, student interviews, and documentation. The results showed that the test questions on mathematical problem-solving ability of KPK and FPB materials were tested to be very valid (validity of 90.90%) for grade V students. The main strength of the two students lies in the instrumental understanding in planning and execution of strategies, as evidenced by the high ability to choose methods and apply algorithms. However, students experience significant limitations in relational understanding, particularly in comprehensively understanding problems and verifying results. This pattern of difficulty includes a failure to identify contextual information and conceptual justification, which indicates reasoning is limited to instrumental-procedural aspects. The implications of learning emphasize the need to develop relational understanding through habituation of contextual problem identification, strengthening conceptual reasoning and verification, and optimizing teaching strategies.

Abstract

Fuzzy time series is a forecasting method that handles data uncertainty by applying fuzzy set theory. This study compares the forecasting accuracy of the Chen fuzzy time series method, modified using Fuzzy C-Means (FCM), and the Lee method in predicting Indonesian coal prices from January 2019 to December 2023. The Chen method is en hanced by generating fuzzy intervals through FCM to better reflect data distribution, while the Lee method uses weighted fuzzy logical relationships. Forecast accuracy is measured using Mean Absolute Percentage Error (MAPE). The modified Chen method achieves a MAPE of 2.56% compared to 5.07% for the Lee method. These results show that cluster ing techniques like FCM can improve fuzzy time series forecasting. This contrasts with earlier studies that favored the Lee method and highlights the potential of adaptive interval construction for volatile commodity prices. The proposed modification offers a promising alternative for improving prediction accuracy in economic time series.
